ABSTRACT:
A photographic support comprises a paper coated on both sides with polyethylene resin film. To impart the paper a desirable stiffness and improved cutting property, polyvinyl alcohol fibers which are neither heat-treated nor acetalized, in 5-20 parts by weight, are mixed to 100 parts by weight of woodpulp fibers when the paper is formed.
